Since many Villains will push ATC here, I would call.

If you are in the BB with under 10 blinds you are supposed to call hands like this regardless; since your hand is slightly better than ATC and you have slightly more than 10 bb's, I think it's an "oh well, what the heck" call.

I dont disagree. I do think in the long run it is less positive equity to limp, and you are more likely to lose a big pot than win one. I am just saying that depending on circumstances (and primarily that is the caliber of players) it might be the right move. I think if you are sufficiently small stacked it can be right. i.e. blinds are 100-200, and you have 2000 (10 BB), you limp, and get a raiser to 600 in mid position, you move all in, and now raiser has 1400 to call and get almost 2 to 1. you have not given away a monster because you might have limped with something like aj, aq, nines, etc, and instead of calling 400 more, you move all in (at least villian might be thinking that). so, now his AJ, or 8s, or whatever he has, might very well look you up. so, my point is that the shorter stacked you, the more "correct" it can be to limp. I just know that I have been in conversations where supposed experts seem to say that is virtually NEVER correct to limp with aces. In my playing time, I have probably done it 10% of the time. who knows if it would have benefitted me to play otherwise.

Of course it is +EV. You have AA and you are putting money in the pot pf. Thats always +EV.

Is it more +EV than a standard raise? very doubtful but, particularly live, you may have a loose passive table that allows you to get away with limping small pairs and weaker suited hands utg and maybe you want to balance that with a few combos of AA and AXs to limp/rr.

Although, Ill concede that Pokerstars isnt the place to find that kind of table.
